HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 763,652, dated June28,1904.

Application filed June 12, 1903.

To all whom, it 7111a, concern.-

Be it known that I, J AMES ALEXANDER AL- LEN, a citizen of theUnitedStates of America, and a resident of the city of Seattle, countyof King, and State of l/Vashington, have invented certain new and usefulImprovements in Hose Couplings, of which the following is aspecification.

My invention relates to improvements in hose-couplings,- and has for itsobject the production of a simplified and inexpensive coupling of thisnature which is durable in use, can be readily connected anddisconnected, and insures a tight joint between the coupling parts.

The above-mentioned and other desirable objects are attained by theconstructions, combinations, and arrangements of parts, as disclosed onthe accompanying drawings, set forth in this specification, andsuccinctly pointed out in the appended claims.

With reference to the drawings filed herewith and bearing like referencecharacters for corresponding parts throughout, Figure l is a view inperspective of my improved coupling, showing the parts disconnected;

and Fig. 2 is a side view of the coupling with the part shown by boldlines in relative position for the final movement to close-theconnection and shows said parts in longitudinal half-section andindicates by broken lines the position of the parts when connected.

This invention includes a pair of tubular coupling parts 3 and 4, whichare formed with suitable tubular stem portions, as 5 and 5,respectively, of the required size to fit within the ends ofhose-sections, as 6, though one of these coupling parts can be formedintegral with a faucet or may be formed with screw-threads on the stemportion for engagement with a pipe-nipple or the like Without departingfrom the essence of the invention,

The coupling part 3 is enlarged in diameter at the head end and isformed with a comparatively deep annular recess or counterbore 7 in thisend as the seat for a resilient packing-ring 8, which preferablycomprises a section of thick rubber tubing whose internal diameter issubstantially equal to the in- Serial'No, 161,213. (No model.)

vternal diameter of stem 5, and this packingring is of suitable lengthto project slightly beyond the outer end of the counterbore when seatedtherein, and serves to pack the joint between the head ends of thecoupling parts "and also yieldingly urge said parts to separate fromeach other when theyare connected together, as will be understood fromthe following. Y

The connection proper between the coupling parts consists of oppositelaterally-projecting lugs-9, secured to the head end of the couplingpart 4:, and preferably formed rectangular in cross-section to affordcomparatively broad side surfaces, and opposite sockets or keepers 10and 11, arranged transversely the head end of coupling part 3 atdiametrically opposite points and formed of suitable size to receivefreely the outer end portions of said lugs, and these sockets or keepersare formed with transverse shoulders, as 15 and 16, respectively, at themouths, which are arranged at suitable separation from each other tostand across the rear side faces of the lugs 9 When they are in place inthe sockets or keepers, and the coupling parts 3 and 4 standsubstantially concentric with each other.

On the rear side face of each lug 9 is a rearwardly-projecting stop 20,which is suitably disposed relatively to the center of the coupling partto lie just within the shoulder in a respective socket or keeper whenthe coupling parts are connected, and thereby prevent lateraldisplacement of the parts relatively to each other. These stops areconveniently provided by forming rabbets in the rear side surfaces ofthe lugs across their outer ends of suitable depth to bring the head endof the coupling part 4 to compress the packing-ring 8 as the couplingparts are connected, and thereby seal the joint and cause thepackingring to yieldingly hold said lugs 9 against the shoulders of thesockets or keepers.

The sockets or keepers 10 and 11 are conveniently incorporated byforming opposite side walls 17 integral with the wall of counterbore 7,and these walls extend slightly forward from the outer end of thecounterbore and project laterally from opposite sides of the head of therespective coupling part and are arranged at suitable separation fromeach other to embrace the projecting end portion of the packing-ring andto receive freely the head end of coupling part 4 and the lugs 9.Between the outer ends of these side walls at one side of the couplingpart is the shoulder 15, which comprises a cross-bar formed integralwith said pieces adjacent their'outer side edges and beveled along theinner side corner, and between the opposite ends of these side walls isthe shoulder 16, which comprises a cross-bar formed integral with saidsides adjacent their outer side edges and extended forwardly therefromto form a longitudinal guide-lip 19, which is inclined inwardly alongthe inner side face from the base to the outer end in conformity withthe sweep of the outer end of the lug 9, which rides thereupon as thecoupling parts are connected, Fig. 2.

To connect the coupling parts, they are grasped in opposite hands andbrought together at an obtuse angle, with one of the lugs 9 inserted inthe socket or keeper 10 and the top surface of the respective stopresting against the under surface of shoulder 15 and the outer end ofthe opposite lug 9 lying against the inclined face of the guide-lip,Fig. 2. This will cause the end of the coupling part 4 to bear upon theouter end of the packing-ring at the base of the lug 9, which is in thesocket or keeper l0, and consequently thepacking-ring will be compressedat this side as the coupling part 1 is pressed downwardly at the outerend to bring the opposite lug 9 to enter the socket or keeper 11, andthis compression of the ring at this side will cause it to shift thecoupling part 4 laterally part 4 over until the outer end portion of theopposite lug 9 engages the shoulder in the socket or keeper l1, and thepressure on the packing-ring will then be equalized.

hen desired to disconnect the coupling, the coupling part 4 is simplypressed upwardly at the outer end, Fig. 2, so as to compress thepacking-ring at the base of the lug 9 in the socket or keeper 10, whenthe stop on said lug will ride the bevel on shoulder 15, and theresiliency of the packing-ring will assist in shifting said couplingpart laterally to disengage the opposite lug 9 from the socket or keeper11.

This coupling is simple and inexpensive of construction and durable inuse, and the parts can be readily connected or disconnected with butslight exertion, while the interposed resilient packing serves toyieldingly secure the coupling parts in interlocked position, and thestops on the lugs prevent lateral displacement of the parts whenconnected.
